Productivity Suite PLC Simulator Software Free Download


The productivity suite software now contains a plc simulator. The software is a free download and is available from automation direct. This software will now allow you to test or troubleshoot your program without the physical hardware present. The entire family of controllers can use the simulator. P1000, P2000, and P3000 emulation can happen on the following parts of the productivity series hardware:
– P1000 CPU’s and local I/O stack, P2000 and P3000 CPU’s and local bases
– All basic I/O modules, both analog and digital
– Modbus TCP Server/Client connections on external Ethernet port

The simulation mode is available on the Productivity Suite version 3.8.x.x or higher. We will be discussing the PAC (Programmable Automation Controller) PLC Simulator. Testing this simulator will be done using our first program (Start-Stop Circuit) and the PID instruction in our Productivity 1000 series. We will also be connecting to physical hardware after using our simulator to test the program. Let’s get started. Keep on Reading!

Productivity P1AM Industrial Arduino PID Control


A Proportional-Integral-Derivative algorithm is a generic Control Loop feedback formula widely used in industrial control systems. A PID algorithm attempts to correct the error between a measured process variable and the desired setpoint by calculating and then outputting a corrective action that can adjust the process accordingly and rapidly, to keep the Error to a minimum.

We will be using an immersion heater in a cup of water to keep the temperature at a constant value.

Productivity Open P1AM Industrial Arduino PID Control

Our immersion heater will be controlled through a relay using time proportional control from our PID output. A J type thermocouple will be used with the P1-04THM thermocouple temperature and voltage input module. The Arduino PID Library by Brett Beauregard will be used with our productivity open P1AM industrial arduino. Our program sketch will use productivity blocks, that will then be verified into the C++ code in the Arduino IDE. Let’s get started. Continue Reading!
